33. B33 CHECK THE P/N_SW/CLUTCH 2 CIRCUIT FOR A SHORT TO VOLTAGE Ignition OFF. Disconnect: CPP Switch C257. Disconnect: RFA Module C3503B. Disconnect: PCM C175B. Ignition ON. Measure the voltage between PCM C175B-7, circuit CE903 (BU/OG), harness side and ground. Is any voltage present? Yes: REPAIR circuit CE903 (BU-OG). CLEAR the DTCs. REPEAT the self-test. TEST the system for normal operation. No: Go to B34 .
34. B34 CHECK THE P/N_SW/CLUTCH 2 INPUT CIRCUIT FOR AN OPEN BETWEEN THE PCM AND RFA MODULE Ignition OFF. Measure the resistance between RFA module C3503B-17, circuit CE903 (BU/OG), harness side and PCM C175B-7, circuit CE903 (BU/OG), harness side. Is the resistance less than 5 ohms? Yes: Go to B35 . No: REPAIR circuit CE903 (BU/OG). CLEAR the DTCs. REPEAT the self-test. TEST the system for normal operation.
35. B35 CHECK THE IPC CLUTCH SWITCH (CLUTCH_INPUT) AND RFA MODULE CLUTCH SWITCH (CLUTCH_SW) PIDs Ignition OFF. Connect: CPP Switch C257. Connect: RFA Module C3503B. Connect: PCM C175B. Ignition ON. Enter the following diagnostic mode on the scan tool: DataLogger- IPC Module. While observing the CLUTCH_INPUT PID, fully engage and disengage the clutch. Enter the following diagnostic mode on the scan tool: DataLogger- RFA module. While observing the CLUTCH _SW PID, fully engage and disengage the clutch. Do both PIDs agree with the clutch pedal position? Yes: The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the self-test. TEST the system for normal operation. No: If the concern is with CPP_BOT PID, INSTALL a new PCM. Refer to «ELECTRONIC ENGINE CONTROLS»(ref-382403) . If the concern is with CLUTCH _SW PID, INSTALL a new RFA module. Refer to «MULTIFUNCTION ELECTRONIC MODULES»(ref-382389) . TEST the system for normal operation.

Pinpoint Test C: DTC P0615:12 or P0617:12

Refer to appropriate SYSTEM WIRING DIAGRAMS article for schematic and connector information.

Note. Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

Pinpoint Test D: Unusual Starter Noise

Refer to appropriate SYSTEM WIRING DIAGRAMS article for schematic and connector information.

Starter Motor - Ground Circuit Test

A no or slow crank condition can be caused by excessive resistance in the ground or return portion of the cranking circuit. Check the voltage drop in the ground circuit as follows

Scheme 41

1. Connect the Fluke 77-IV Digital Multimeter positive lead to the starter motor housing (make sure the connection is clean and free of rust or grease). Connect the negative lead to the negative (-) battery terminal.
2. Engage the remote starter switch and crank the engine. Read and record the voltage reading. The reading should be 0.5 volt or less.
3. If the voltage is greater than 0.5 volt, clean the negative cable connections at the battery, the body ground connections and the starter ground connections. Retest.
4. If the voltage is greater than 0.5 volt, install a new negative battery cable. If the voltage reading is less than 0.5 volt and the engine still does not crank or cranks slowly, install a new starter motor.
